Your results will appear here.
Enter your values and press Calculate.
Enter the number of hives, how many minutes a single hive inspection takes you, and how many inspections you plan per hive per year. The calculator returns the hours one full inspection round takes, the total hours for the year, and the total number of hive inspections. Use the seasonal schedule below to pick a sensible inspections-per-year figure: swarm season needs a visit every 7 days, while winter needs almost none. These are planning estimates for hobby beekeeping, not veterinary advice.
The maths is simple on purpose. One inspection round costs hives × minutes per inspection, divided by 60 to get hours. Multiply by inspections per year for the annual time budget, and multiply hives by inspections per year for the visit count.
Worked example: 10 hives at 20 minutes per inspection take 200 minutes, or 3.33 hours, per round. At 12 inspections per hive per year, that is 40 hours a year and 120 hive inspections in total. A second example: 4 hives at 30 minutes each take 2 hours per round, and at 20 inspections a year that is 40 hours a year across 80 inspections. The number that usually surprises new beekeepers is the annual total, which is why planning it matters before adding hives.
Guides agree on the shape of the season even when they differ on exact days. Inspect about every two weeks during spring, summer and early fall, and check sooner if the hive is new or you see a problem. In winter, do not open the hive unless the weather is calm and above 55 degrees Fahrenheit.
| Season | Typical interval | |---|---| | Early spring, buildup | Every 7 to 10 days | | Late spring, swarm season | Every 7 days | | Summer, nectar flow | Every 10 to 14 days | | Late summer, fall prep | Every 14 to 21 days | | Winter, cold climates | Do not open, check weight and activity | | Winter, mild climates | Monthly quick checks on warm days |
The tightest interval is set by queen development: a queen cell is capped roughly eight days after the egg is laid, so returning on the seventh day means any cell started since your last visit is still open and countable. Beginners are usually advised every 7 to 10 days, while experienced keepers inspect seasonally or as needed, watching entrance activity, pollen flow and hive weight between visits.
This frequency guidance is the beehive inspection frequency most guides repeat, and the seasonal table above is your hive inspection scheduler and timing reference: use it to set inspection timing for beehives through summer, and to check beehives on the same rhythm each season.
Competitor guides draw a useful distinction. A hive check, every two weeks except in winter, pulls just a few frames to verify the queen is laying and resources are adequate. A full hive inspection, typically four times per year (February before spring buildup, April or May before supering, July or August after the honey flow, and October or November going into winter), assesses queen quality, brood pattern and population, checks for pests and disease, adjusts space, and covers mite testing and treatment.
Budget your time accordingly: a quick check can take five to seven minutes per hive, while a full inspection takes 30 to 60 minutes per hive. Enter the figure that matches the visit type you are planning, or run the calculator twice, once for checks and once for full inspections, and add the two annual totals.
Use the same short checklist on every visit so changes stand out. Check brood (eggs, young bees and capped brood), queen activity (a steady laying pattern; you do not need to find the queen every time), food (pollen, nectar and capped honey), space (room for brood and food, without so much empty space that pests move in), pests and disease (Varroa mites, damaged or spotty brood, small hive beetles), and hive condition (secure boxes, dry equipment, clear entrance, good airflow).
Inspect sooner than planned if you notice a fast drop in bee activity during warm weather, a swarm or many queen cells, very light food stores, damaged or spotty brood, signs of mites or disease, or damage from wind, animals or water. Keep a short record after every visit: date, weather, brood pattern, food stores, mite check, available space and any action taken.
Pick a warm, calm day for a full inspection, ideally above 55 degrees Fahrenheit, and work between about 10am and 4pm in the warm season when foragers are out and the hive is calmer. In winter, keep the hive closed and watch the entrance, clear snow, and check hive weight with as little disturbance as possible. If you must lift the lid in winter, choose a calm day above 55 degrees and work fast, because cold or windy weather can chill or kill bees.
Avoid inspecting late in the evening or at night, when foragers are home and defensive, and avoid opening a hive in rain or strong wind. New packages get a short check on day 3 or 4 to confirm the queen has left her cage, then again at day 7 to 10 to look for eggs. After a swarm, wait at least 7 days before checking, and look for the queen or eggs.
No nectar and a light hive means feed immediately. Running out of space in a single deep means add another brood box or a medium box or super, depending on the time of year. A double deep out of space means split the hive or add a honey super. Seeing mites or poor brood means test for Varroa mites and treat if necessary, and requeen if the brood pattern stays poor.
Too few bees for the space means reduce boxes or combine colonies; too many bees means split or add boxes. As a rough bee-to-box guide, one supplier guide suggests 5 or more frames of bees in January, 8 or more in March, 14 or more in May, and 12 or more in November. Inspecting too often also has a cost: each opening sets the colony back, so keep visits intentional, get in, assess what is needed, and get out.
About every two weeks during spring, summer and early fall, and sooner if the hive is new or you see a problem. In winter, do not open the hive unless the weather is calm and above 55 degrees Fahrenheit.
Every 7 to 10 days during early spring buildup, tightening to every 7 days in late spring swarm season, because a queen cell is capped roughly eight days after the egg is laid and a 7-day return catches cells before capping.
In cold climates, no: check weight and entrance activity instead, and keep the cluster sealed. In mild climates, a monthly quick check on a warm, calm day above 55 degrees is acceptable, but work fast and do not break the cluster.
Because queen cells are capped about eight days after the egg is laid. Returning every seven days in swarm season means any cell started since your last visit is still open and countable, so you can act before a swarm leaves.
A quick hive check takes about five to seven minutes per hive. A full inspection takes 30 to 60 minutes per hive. Enter the figure that matches your visit type in this calculator to budget the round honestly.
Wait at least 7 days after a swarm, then check for the queen or for eggs. Checking sooner disturbs a colony that is still settling and may not yet show whether a new queen is laying.
For a full inspection, choose a calm day above 55 degrees Fahrenheit. Bees cannot fly below about 50 degrees, and cold or windy weather can chill brood and kill bees, so winter openings should be rare and brief.
After installing a package, make a short check on day 3 or 4 to confirm the queen has left her cage, then check again at day 7 to 10 for eggs. Use the five-point checklist: brood, queen activity, food, space, and pests and disease.
No. At night the foragers are home, the colony is defensive, and you cannot judge brood, stores or bee behaviour properly. Inspect in the warm part of the day, roughly 10am to 4pm in the warm season.
No. Eggs and a steady brood pattern prove the queen is laying. Finding her every time disturbs the colony for no benefit; scan for her early if you do look, and be gentle if you see her.
